Welcome to the army of users whose operating system and/or antimalware thinks TPT is a virus. We can't do anything about it other than shoving a hash of the binary down every single (anti?)malware vendor's throat out there every time there's a new version. Which we may or may not do, depending on how annoying it is to do. What *you* can and should do is add an exception for TPT in Defender.
Open windows search and search for "App & Browser Control"
There should be an option "Check apps and files". There are 3 options, Block, Warn, and Off. You have it set to "Block", which blocks everything from running downloaded from the internet, regardless of what it is. Change it to either Warn and you'll be able to run TPT.
when you have windows defender on and it says " windows protected your pc" click on more info and a button will appear that says "run anyway" than it will run.
